Did you even read the OP? 3rd line of the post:

"Many people have bought mosquito traps that advertise their ability to attract mosquitoes, either by CO2, UV light, Octenol, etc., but most of the time, it does not work."

The trap you posted:

"CARBON DIOXIDE is the primary bait used and is produced by the photocatalyst reaction of the UV rays radiating onto a panel coated with Titanium Dioxide (TiO2). As a catalyst, TiO2 is not consumed in the process.The mosquito is sensitive to the wavelength of light of the UV RAYS and the PERMANENT HEAT from the UV lamp tube serve as another attractant to the mosquitoes.

OCTENOL and LACTIC ACID are added to help lure mosquitoes toward the trap, where they are then suctioned in by the fan. The Lactic-Acid & Octenol lasts approximately two (2) months."

Well done.
